CAR BURETER FOR MOTOR-CARS, 61.0;

Application filed Harch23,1 903.

To 1.1.1!- whm'n, at party conpern: Be it :n that we,J AMEs FREDERICK BEN- r5" l trical engineer, residing atl8Violet llicld, and HEDLEY STANLEY Moosgineer, residing at Glenwood, Dore, 1d, England, subjects of the King of Great Britain, have invented certain new and useful Improvements in 'Carbureters for Motor-(Jars and other Purposes, of which the fol-' lowing is a specification. 1

Our invention has for its objectacarbureter which will .work with light and heavy oils, alcohol, and other forms of volatile liquid.

The apparatus consists of three partsnamely, anautomatic feed, a heater, and a miker which brings the elements into perfect mixture with each other when the air and oil are heated. V

Figure 1 is a sectional side elevation of the apparatus. ofthe feed. Fig. 3 is a plan of the feed.

Figs. 4 and 6 are sectional side elevations of modified forms of heater. -Fig. 5 is a local section on the line 5 5, Fig. 1.

The automatic feed consists of a .valve It, worked by the suction of the engine against a spring I). The valve-seat 0 (shown separately at Fig. 2) has in it ports 0' a, one or both of these being wider at one end than the other. .These ports'are in front of the oil and air inlets (i d, and by rotating the seat by meansof the handle 0', Fig.9.. 1 and 3, the supply canbe regulated.

. Thejheater consists of a. coil eih a casing e. heated by the exhaust or by hot water from the cylinderdaoket, which may either fill the casing, circulating through openings 0 Fig. 1, or be led through a pipe fin it, as shown at Fig. 6. At the bottom of the casing is a cup gpFig, 4, in which spirit is burned at starting, or the casing may have a due it, Fig. 1, through it, so that it is heatediat starting by'a lamp'j. The oil and air pass from the heater to the annular chamber Z of the mixer and from thence escape by radial jets i into a I central pipe in. one end of which opens into a chamber m", supplied with air by a cock W12,

while the other end opens into a chamber 1",

Fig. 2 is a plan of the valve-seat.

able openings 02. to complete a perfect explosive mixture.

The whole apparatus acts as follows:. Air. and oil is drawn into the feed and then passes into the heater and is raised to the required; temperature. It is then passed on to the mixer and converted into a finely-divided A .conven'ient'mcans of heating is to start the engine with spirit, and when all is hot to turn off the spirit and turn on the parafiin. I

It is found in practice that the auton'i'atic feed may be placed at the mixer end of coil in which case the oil does not pass through the heater; but there may be a separate coil 'for heating the oil, which is heated by heater or other convenient means.

' The heat may be adjusted by means of a tank 0, Fig. 6, containing water or any liquid which boilsat the heat required. This may flow into the casing of the heater by gravity or pressure.

When the casing is heated by the exhaust or other source of heat, the vapor of the internal liquid drives it into the tank. the casing is kept at the boiling-point of the liquid.

The tank 0 is a circulating one containing water or other liquid and has a pressure blowofi'valve 0'. ..'.lhc carlmretcr-jackut also con tains the liquid and is connected to the tank by two pipes If n. Thus when the carburetor becomes heated to a given temperature the liquid is evaporated, producing steam or vapor,-thus absorbingthe heat and keeping the carburet'er at a constant temperature. It will readily be seen that the temperature-i of the carburetor depends on the weight on the safety-valve. By liberating or compressing" same we get a higher or lower tempcratu re.

What we claim is-- '1. In a mixer for a carbureter, the combination of a pipe, means for supplying air to one end of the pipe, jets directed inward radially to the pipe, means for supplying vapor to the jets. a vessel connected to the other end of the pipe, and means for supplying further air to the vessel.

2: in a mixer. for a carburetor, the combi- .ipation of a pipe, means for supplying air to one end of the pipe, an annular chamber surrounding the pipe. passages leading radially inward from the chamber to the pipe, means for supplying vapor to the ehamber, a vessel connectedto the other end of the pipe, and means for supplying further air to the vessel.

3. lna lrvdreearhon feed for a earbureter the combination of a block having in it passages for the supp y of air and hydrocarbon, a valve-seat resting on the block and having in it two circular slots one of which is wider j at one end then the other, means for rotating the valve se'at about the center of the slots, and a valve resting on the seat. I

4. In a hydrocarbon-feed for a e'arbureter, the combination of-a block having in it a central hole and passages for the supply of air and hydrocarbon equidistant from the hole a sleeve working'in the hole, a handle fixed to one end of the sleeve, a valve-seat resting on the blockand fixed to the other end of the sleeve and having in it'two circular slots one on wl ich is wider at one end than the other, dle passing through the sleeve; aspring aetinQori the spiudle,'and a valve fixed to the spindle and resting on the seat.
